312 ANNUAL "REPORT OF THE Off. Doc. 



September 6, 1906, at the rate of two bushels to the acre with 200 

 pounds of a fertilizer containing 10 per cent, phosphoric acid and 2 

 per cent, of potash. Four days after the wheat was sown a heavy 

 rain fell which compacted the soil some, but did not prevent the 

 wheat from comiug up regularly. 



The field was examined November 8, 1906. At this time the wheat 

 was from 16 to 19 inches tall when the leaves were drawn up to 

 three full lengths, but was not as dark green a color as Mr. Dietz's. 

 The wheat had stooled well having from two to three tillers to the 

 stool. It was exceedingly heavy on the ground so that a large 

 number of lower leaves had turned yellow for want of sunlight. 

 The wheat went into winter in this condition and was so heavy that 

 the field mice did some damage. 



The field was again inspected April 12, 1907. At this time the 16 

 to 19 inch leaves had died down to from 11 to 13 inches and some 

 even down to the stem. The color was pale green and did not look 

 vigorous. Some of the tillers evidently the tallest and those that 

 had grown most vigorously had been winter-killed to such a degree 

 that at this time it seemed as if the tillers that had not made so 

 vigorous a growth in the fall would develop into the best stools now. 

 It was a question at this time how many of the tillers would develop. 

 The fly had done some damage in the fall but at this spring examina- 

 tion it seemed about all dead. May 27, 1907, this field was again 

 examined. At this time the color was a dark green and the wheat 

 stood well and was strong in the stem. Approximately twenty-two 

 per cent, of the stools had more than one tiller and these came 

 largely from the stools that had not grown so vigorously in the fall. 

 The straw of the stools with one tiller was from 27 to 34 inches tall 

 while that in the stools with more than one tiller was from three to. 

 eix inches shorter. The heads were formed but were still in the 

 sheath. Little damage had been done by the spring brood of the fly 

 up to this time. This field was inspected the last time July 2. At 

 this time the wheat was ripening. The straw stiff and strong and 

 none had lodged. But the stand was too thin, because the stools 

 that had more than one tiller usually developed only one head. Some 

 times two smaller heads developed, and sometimes a larger one and 

 a smaller one. When there was only one tiller to the stool the straw 

 varied in height from 50 to 63 inches and in stools with one large and 

 one small tiller from 47 to 53 inches and in stools with two equal 

 tillers from 47 to 48 inches. The heads on the stools with more than 

 one tiller varied in length from one and a half to two and a half 

 inches, while those on the one tilled stools were from 3^ to 4 inches 

 long. The grains in the larger heads were plump and large and the 

 grains in the smaller heads were smaller. The spring brood of flies 

 did little damage to this wheat, only here and there a stalk. This 

 wheat was harvested July 16, put in shock until thoroughly dried 

 and was housed in a large barn and threshed August 30, 1907, and 

 yielded 31 bushels cleaned field yield per acre. 98 per cent, of the 

 kernels were similar in shape, the color, the bright and clear color 

 of red wheat. The size of the kernels was fairly uniform. Ten grains 

 of an average sample laid end to end, measure two and five-eighth 

 inches. There are no weed seeds and dirt in the cleaned wheat as 

 it was used for seed. About two per cent, of the grains are damaged 

 by the thresher, 9?' per cent, of these grains are plump. The bran
